Patent DE-3638229-A1 (DE)
Title: Channel-type (core-type) induction furnace
Inventor: WICKER HELMUT DIPL ING
IPC: H05B6/06
Filed: 1986-11-08
Abstract: The invention relates to a channel-type induction furnace in which a grooved channel is filled with melt and this filled melt channel at the same time forms the secondary winding of the inductor. The channel-type inductor can be connected directly to the electrical mains power supply (50 or 60 Hz). Pinching forces occur in the channel at high powers, and the ceramic cladding of the channel-type inductors is destroyed by cavitation phenomena in the event of the pinching forces being high. The invention indicates a means of considerably increasing the power of a channel-type inductor without pinching forces or cavitation occurring; the invention can also be used for already existing channel-type inductors. This is achieved in that the channel-type inductor is operated using alternating current at a frequency in the range from 80 to 500 Hz, via a frequency converter. At the same time, the frequency converter results in the load, which is intrinsically of a single-phase type and represents the inductor, being distributed in a balanced manner between the three phases of an electrical mains power supply.

Title: Method for reducing a digital noise signal comprising a sequence of pulsed interference in a digital input signal and circuit arrangement to carry out this method
Inventor: BILLMANN LOTHAR DR
IPC: H03K5/1252
Filed: 1987-03-26
Abstract: The invention relates to a method for reducing a digital noise signal comprising a sequence of pulsed interference and a digital circuit arrangement to carry out this method. The digital input signal (Xe) comprising a digital useful signal and the digital noise signal is used as the output signal (Xa) of this circuit arrangement if the magnitude of the difference between the input signal value (Xe) and the output signal value (Xa) delayed by one clock cycle is no greater than a predefined value (G) which is equal to the magnitude of the maximum possible change in two consecutive useful signal values. If, however, the aforementioned magnitude is greater than the predefined value (G), a low-pass-filtered signal (Xr) generated from the input signal (Xe) is used as the output signal (Xa). The value of the input signal (Xe) delayed by one clock cycle is used to provide initial values in the low-pass filtering. <IMAGE>

Title: Process and system for producing cement clinker from raw cement slurry
Inventor: KREFT WILFRIED DIPL ING
IPC: F27B7/20
Filed: 1987-04-02
Abstract: The invention relates to the production of cement clinker from pumpable raw cement slurry which is first dried to form raw cement meal, whereupon said raw cement meal is preheated in a multistage suspension preheater and is then calcined in a calcining kiln to form cement clinker. An especially economical process and a plant of relatively simple construction are produced in that the pumpable raw cement slurry is first mixed with a partial amount of dry raw cement meal from an upper stage of the suspension preheater and is then dried in a pneumatic conveying drier to form raw cement meal ready for the kiln (as a feed product for the suspension preheater).
Patent DE-3711198-A1 (DE)
Title: Impeller wheel
Inventor: SIEGERIST H G
IPC: F04D3/00
Filed: 1987-04-02
Abstract: The invention concerns an impeller wheel, in particular for ship propulsion, but also suitable for pumps. The drive to the outer diameter of the gear rim can be provided directly from the propelling engine via intermediate shafts, or via hydraulic or electric motors, etc. At present, ships' propellers are driven by means of a centrally positioned shaft. Due to the drive shaft and the ship's hull, there are incident-flow and filling losses around the afterbody. In the invention, these incident-flow and filling losses do not occur, since the area of the afterbody, and here the area for the stern tube, can be eliminated. Since the impeller wheel is thus free in the water under the ship, the losses are also eliminated. A further advantage provided by the gear rim that exists as a bearer for the impeller blades is that part of the accelerated masses of water is not displaced outwards by centrifugal force, but is also guided into an ordered flow by the gear rim. The number of blades and their angle of incident-flow and shape is designed according to the application. The revolving gear rim is located in a closed, faired annular body, from which the propulsion occurs and where the bearing is also located. The impeller blades can be mounted facing one another in the centring point, or on a central shaft. On the outer circumference... Original abstract incomplete.

Title: Ultrasonic lithotripter
Inventor: FLACHENECKER GERHARD PROF DR I
IPC: A61B17/22
Filed: 1987-04-09
Abstract: The invention relates to an ultrasonic lithotripter for destroying and removing stone concretions in the human body, i.e., e.g., bladder stones (cystoliths), kidney stones, ureteroliths and gall stones. It consists of a piezoelectric transducer and a probe, which can be brought up to the stone located inside the patient. The piezoelectric transducer is fed from a radio-frequency generator. A ladder network of two acoustic transformers is provided between the piezoelectric transducer and the probe. The first acoustic transformer is rigidly connected to the clamping system of the piezoelectric transducer and the second acoustic transformer is rigidly connected to the probe. A detachable connection such as, e.g., a screw connection is located between the two acoustic transformers. As a result, the probe can be removed from the remaining part of the lithotripter and replaced by other probes. The second acoustic transformer is specially dimensioned for each shape of probe, so that for each shape of probe the appropriate power is transmitted from the radio-frequency generator to the piezoelectric transducer and thus to the probe. The advantage of the arrangement consists in that the lithotripter can be adapted to any application by a simple exchange of the probe, and the appropriate power is always automatically transmitted to the respective probe. <IMAGE>

Title: Hydrodynamic reversing gear
Inventor: MUELLER HELMUT
IPC: F16H47/07
Filed: 1987-06-29
Abstract: The invention concerns hydrodynamic reversing gearing, in particular a ship's reversing gear, that has two fluid clutches, of which one, assigned to going ahead, is fastened directly to the drive shaft and drives a driven pinion. A second clutch is connected to the drive shaft by way of a reversing gearbox, and also drives the driven pinion, for going astern. Both clutches are controlled by filling and emptying; to reduce their dimensions and the wall friction losses, they are fitted with slanted blades. At least the fluid clutch assigned to going astern also has movable flow barriers, in order to reduce the windage while going ahead. By means of a control device, it is possible to operate the propeller at even lower r.p.m. than the idling speed of the prime mover.
